IMPROVED HINGE.

The Schedule referred to ln these Letters Patent and making part of the name.

Specification of certain Improvements in. Hinges, invented by JOHN J. Oaookn, of Smitheld, in the county of Richmond, andfState of New Yprk, and LEWIS Cnooxn and HENRY S. Cnoolrn, of the city, county, and State of New York.;

VNature and 'Ojccts of the Invention.

. This invention has relation to'V the manner of se-v curing the pin or axis of the hinge in position,- and consists of the improvements hereinafter described,

efiectually seby which the said pin or axis is more cured from accidental or forcibledisplacement, and

-from displacement in consequence of thejveai'ing of the parts.

General Description.

The wings A and B of the hinge are first made of wrought or malleable metal, in any of the usual forms, and this having been done, we theni'orm a cylindrical recess in each end of the joint, and also a groove around this recess, as shown in tig. 3, which groove `ive prefer to make in the form of a V, the outer side thereof being cylindrical.

XVe then insert the pin C in position, as shown in igs. 3 and 4, leaving room in the ends of the hinge for the end-pins, or pieces .D and E, as shown,'which fare then inserted in place.

These pins D and E'are formed with, .round `or con- 'veit heads F, like those of the common rivet, as shown,

and these heads made. concave on the under side, to

t into \the recesses already mentioned, and bear at their outer edges upon the metal of the joint.

The lengthofthe pins C, D, and E, when takento'- gether, is -also such as to allow for a little upsetting ot' the metal, in the process of' securing the parts in position, without compressing the jointof the hinge.`V

The parts having been thus put together, we then, with a proper tool, or punch, orA swage, swage down that portion of the metal which forms the inner side instead of being joined to the parts D and hang, and secure the heads Fof the parts D and E,

from displacement; and at the same time, and with the same tool, we also slightly swage down the heads F- oi' the parts D and E, so as' to canse them to perfectly lill the wholeV diameter of' the recesses, and press the metal of' 'the wing of' the hinge under the heads of these parts, closely around' their Shanks, as shown in igpfl, Vthe 'tool beingmade in such form as to accomplish all. these purposes.

' 'For greater uniformity, andlgreater facility of execution, weY prefer to perform these operations, last described, ina press, having the proper tools inserted thereinv forthat purpose. Y

. In fig.r5, vinstead of the centre-pin being made in threerpieces, 0,1), and E, as shown in figs. 3 and 4,

it is represented as being made in two parts, the division `heingin the centre; and ing. 6 it is represented as being made in two parts, with the division near one end, and the head F formed on one end ot' each of these parts, as shown.

- It is also obvious that the construction we have de-` scribed may be still further modilied, by making the pin C long enough to fill nearly the whole length of the joint, and making the heads or bosses F, separate, E and which may be secured in place byswaging iii the same manner. When such caps are used, they may be made `from the punchings from the holesfor the screws.

Remarks.

The construction above described secures the axis of the hinge perfectly against accidental displacement, and the making 'of this pin in parts allows the necessary heads to be formed .upon theparts having heads before they are inserted in the joint, and the same advantage is gained without shanks, as already described. I

The parts D and E may also be made ornamental at their outerends, if desired.

This invention also has the advantages over that of simply swaging' down the metal over the ordinary cylindrical joint-pin, that, by the enlargement of the diameter ofthe port-ion swaged down, it gives a great" amount of metal, and, consequently, greater strength and further, that by furnishing a shoulder inside, or toward thelrniddle ofthe hinge from the part swaged,

it prevents the pin from being driven out or displaced'. byeXtra-neous force.

. This invention may be applied'to the Aconstruction of either but or strap-hinges.
